An 82-year old man was admitted to our hospital for evaluation of progressive general malaise. He had previously been in good health. His chest roentgenogram showed reticular shadows and we suspected interstitial lung disease. On admission, his roentgenographic images showed deterioration compared with previous images. Acute lung injury was diagnosed by(More)
TGF-beta signals through TGF-beta receptors and Smad proteins. TGF-beta also augments fibroblast-mediated collagen gel contraction, an in vitro model of connective tissue remodeling. To investigate the importance of Smad2 or Smad3 in this augmentation process, embryo-derived fibroblasts from mice lacking expression of Smad2 or Smad3 genes were cast into(More)
Bone marrow (stem/progenitor) cells have been shown to "differentiate" into cells in multiple tissues, including lung. A low number of hematopoietic stem/progenitor cells also circulate in peripheral blood. The physiologic roles of these cells are still uncertain. This study was designed to test, using parabiotic mice that were joined surgically, whether(More)
Nerve growth factor (NGF), a polypeptide with well-known actions on neurons, is believed to play a role in the process of tissue repair. The aim of this study was to investigate the effect of NGF on human fetal lung fibroblast (HFL-1)-mediated type I collagen gel contraction and on chemotaxis of the cells with the use of the blind-well chamber technique.(More)
We conducted a pilot study to prospectively evaluate the efficacy of PET/CT with 11C-choline (choline PET/CT) for primary diagnosis and staging of urothelial carcinoma of the upper urinary tract (UUT-UC). Enrolled in this study were 16 patients (9 men, 7 women; age range 51 – 83 years, mean ± SD 69 ± 10.8 years) with suspected UUT-UC. The patients were(More)
UNLABELLED Earlier investigations showed that N-isopropyl-p-123I-iodoamphetamine SPECT (123I-IMP SPECT) is useful for the diagnosis of uveal malignant melanoma, whereas the feasibility and usefulness of 18F-FDG PET in uveal malignant melanoma have not yet been established. We compared the usefulness of 123I-IMP SPECT and 18F-FDG PET for the detection of(More)
We propose a real-time gaze estimation method based on facial-feature tracking using a single video camera that does not require any special user action for calibration. Many gaze estimation methods have been already proposed; however, most conventional gaze tracking algorithms can only be applied to experimental environments due to their complex(More)
The development of new and useful pharmaceutical drugs is essential in order to improve the quality of drug therapeutics. Clinical trials play a central role in drug development. Over time, the clinical trial infrastructure has improved and is now integrating the contribution of clinical research coordinators (CRC). Nevertheless, the attitude of doctors(More)
BACKGROUND T(H)2 and T(H)1 cytokines have opposite effects on many aspects of the inflammatory response. METHODS This study was designed to determine if cytokines possibly present in asthma can modulate airway smooth muscle cell (ASMC) production of vascular endothelial growth factor (VEGF) and thus contribute to altered airway vascularity. ASMC were(More)
Cell migration and matrix remodeling are key events in tissue repair and restructuring. Osteoblasts are responsible for the production of new bone matrix during bone remodeling. The activity of these cells can be modulated by a number of factors. The current study evaluated the hypothesis that cigarette smoke extract can alter repair and remodeling(More)
